A Security Vulnerability in the Solaris i915 DRM Driver May Cause a Kernel Panic

1. Impact

An insufficient resource management security vulnerability in the Solaris i915 Direct Rendering Manager (DRM) kernel driver (i915(7d)) may allow an unprivileged
local user to overwrite arbitrary portions of kernel memory, which may
cause a kernel panic. This is a type of denial of service (DoS).

2. The i915 driver is not available for the SPARC platform, hence
OpenSolaris on the SPARC platform is not vulnerable to the issue.

3. Only OpenSolaris installations which include the affected i915 kernel driver are impacted by this issue.

4. OpenSolaris distributions may include additional bug fixes above and
beyond the build from which it was derived. The base build can be
derived as follows:

$ uname -vsnv_86

3. Symptoms

There are no predictable symptoms that would indicate the described
issue has occurred.

4. Workaround

There is no workaround for this issue. Please see the Resolution
section below.

5. Resolution

This issue is addressed in the following releases:

x86 Platform:

OpenSolaris based upon builds snv_103 or later
